Questions and Answers

What is tissue culture?

  • The in vivo culture of cells, tissues, organs, or whole plants under controlled nutritional and environmental conditions
  • The in vitro culture of cells, tissues, organs, or whole plants under uncontrolled nutritional and environmental conditions
  • The in vivo culture of cells, tissues, organs, or whole plants under uncontrolled nutritional and environmental conditions
  • The in vitro aseptic culture of cells, tissues, organs, or whole plants under controlled nutritional and environmental conditions (correct)
  • What factors are included in the controlled conditions for tissue culture?

  • Random supply of nutrients, acidic medium, fluctuating temperature, and uncontrolled gaseous and liquid environment
  • Proper supply of nutrients, pH medium, adequate temperature, and proper gaseous and liquid environment (correct)
  • Limited supply of nutrients, basic medium, extreme temperature, and uncontrolled gaseous and liquid environment
  • Excessive supply of nutrients, neutral medium, constant temperature, and uncontrolled gaseous and liquid environment

    Study Notes

    Current and Future Status of Plant Tissue Culture

    • Plant cell biotechnology has evolved as a new era in the field of biotechnology, focusing on the production of a large number of secondary plant products.
    • Genetic engineering and molecular biology techniques have allowed the development of improved and new agricultural products, leading to an increasing demand in several countries worldwide.
    • Tissue culture techniques provided the tools for the introduction of genetic information into plant cells, enabling the production of proteins and medicinal substances in transgenic plants.
    • Transgenic plants represent an economical alternative to fermentation-based production systems and are especially promising for producing vaccines and antibodies.
    • The number of farmers who incorporated transgenic plants into their production systems was 13.3 million in 2008, compared to 11 million in 2007.
    • Micropropagation starts with the selection of plant tissues (explant) from a healthy, vigorous mother plant, and any part of the plant can be used as explant.
    • The stages of micropropagation include preparation of the donor plant, initiation stage, multiplication stage, rooting stage, and acclimatization stage.
    • Somatic embryogenesis is an in vitro method of plant regeneration widely used for sustained clonal propagation, involving somatic cells or tissues developing into differentiated embryos.
    • Somatic embryogenesis can be initiated directly from the explants or indirectly by the establishment of mass of unorganized cells named callus.
    • Plant regeneration via organogenesis involves the production of plant organs directly from the meristem or indirectly from undifferentiated cell masses (callus).
    • Somatic embryogenesis and organogenesis are valuable tools for genetic manipulation, developing plants resistant to various stresses, and introducing genes by genetic transformation.
    • Factors such as plant growth regulators and a highly efficient protocol have been reported to affect the induction and development of somatic embryos in cultured cells.
